Title: Flowmeter
Inventor: NABESHIMA NORIYUKI
IPC: G01F15/075
Filed: 1990-01-09
Abstract: PURPOSE:To achieve low power consumption by judging the forward and reverse rotations only in a low-rotation region, and making the frequency of the sampling pulses of either one sensor lower than that of the other sensor. CONSTITUTION:The output pulse of an oscillator 12 is converted into the pulse having the short width with a monostable circuit 13. A frequency divider 14 decreases the frequency of the output pulses from the oscillator, e.g. 500 Hz, to 100 Hz. The sampling pulses from the circuit 13 and the frequency divider 14 are applied as the currents and the voltages for sensor parts 1 and 6. The phases of the output signals of the sensor parts 1 and 6 are compared so as to judge forward rotation or reverse rotation. The output signal of the sensor 1 is added at the time of the forward rotation and subtracted at the time of the reverse rotation. Thus the computation is performed. At this time, a frequency f2 which is applied to the sensor part 6 is made lower than a frequency f1 of the sampling pulses applied on the sensor part 1. At the time of high-speed rotation when the number of rotations exceeds a specified value, the judgment for the forward and reverse rotations is not performed. The output of the sensor part 1 is added or subtracted based on the rotating direction immediately before the number of rotations exceeds the specified value. Thus the computation is performed. For example, when the rotating direction immediately before is the forward rotation, the outputs of the sensor part 1 are continuously added.

Filed: 1995-01-12
Abstract: PURPOSE: To keep the intensity of a laser beam for the irradiation on an object to be machined constant by detecting the degree of stain on the window member through which a laser beam transmits for machining and thereby controlling the intensity of the incident laser beam. CONSTITUTION: When an object 8 to be machined is irradiated with a laser beam L, scattered substances from the machining stick to a trap window member 7. The intensity of the laser beam L transmitting the trap window member 7 is detected from time to time by a sensor 18. At the time of the detecting, the supporting member 17a of a reflecting mirror 16 is driven by a driving source 17b, advancing the reflection mirror 16 to the light path of the laser beam L. The laser beam L is thereby reflected on the reflecting mirror 16 and made incident on a sensor 18; therefore, the intensity is detected. The detected signal is inputted in a controller 21 and compared with a set value; accordingly, a driving signal is outputted to a laser oscillator, increasing the intensity of the laser beam L.  As a result, the intensity of the laser beam L is kept constant regardless of the degree of stain on the trap window member 7.

Title: Unmanned carrying device
Inventor: SHIMADA YOSHIAKI
IPC: G05D1/02
Filed: 1988-01-12
Abstract: PURPOSE:To avoid the deviation and variance of the stopping positions of an unmanned carrier due to the variance of the running speed and the traveling direction of the carrier and to omit the control of a timer by selecting an E-shaped plane form of a stop point detecting iron piece and setting two detecting points for stoppage of the carrier. CONSTITUTION:An unmanned carrier 1 is driven along a guide line 2 embedded in a traveling path and decelerated with reception of the signal from a stop command line 3 also embedded in the driving path. When a foot part 7 of a stop point detecting iron piece 6 is detected, the preparation is started for stoppage of the carrier 1. Then the carrier 3 is stopped after detection of a foot part 8. In a backward drive mode the preparation for stoppage of the carrier 1 is started with detection of a foot part 9. In such a way, two points, i.e., a stop preparation point and a stop point are set for detection of the stoppage. Then the stop preparation is carried out when the piece 6 is detected for a fixed time or more during the reception of a low frequency current supplied to the line 3. The carrier 1 is stopped with the next detection of the piece 6. Thus it is possible to prevent the deviation and variance of the carrier 1 due to the variance of the running speed and the traveling directions of the carrier 1 and to omit the control of a timer.
